SUTXTAPER - TAPER in (X,T) the edges of a data panel to zero.
sutxtaper stdout [optional parameters]
Optional Parameters:
low=0. minimum amplitude factor of taper
tbeg=0 length of taper (ms) at trace start
tend=0 length of taper (ms) at trace end
taper=1 taper type
=1 linear (default)
=2 sine
=3 cosine
=4 gaussian (+/-3.8)
=5 gaussian (+/-2.0)
key=tr set key to compute x-domain taper weights
default is using internal tracecount (tr)
tr1=0 number of traces to be tapered at beg (key=tr)
tr2=tr1 number of traces to be tapered at end (key=tr)
min=0. minimum value of key where taper starts (amp=1.)
max=0. maximum value of key where taper starts (amp=1.)
dx=1. length of taper (in key units)
if key=tr (unset) length is tr1 and (ntr-tr2)
Notes:
Taper type is used for trace (x-domain) tapering as well
as for time domain tapering.
The taper is applied to all traces tr2 (or key >max) and all time samples tend.
Taper weights are amp*1 for traces n tr1
